The flag and the coat-of-arms of the district of Reinickendorf were officially adopted on 28th November 1955. Ratio 3:5. The territory of Reinickendorf did not change in the Berlin district reform of January 2001, thus the flag and coat-of-arms are still valid.

The arms were granted on November 28, 1955. The arms are based on the old village seal, which showed a landscape with a canting fox (Rein is the name of a fox in some legends), some trees and a field of wheat. This seal was also used until 1955 as arms. In the arms the bunch of wheat was replaced by six wheat-ears (...) symbolising the six former villages. As with all arms of the Berlin districts, a mural crown with a small shield with the arms of Berlin may be used.
